Question about RCA HD52W56 52" Rear Projection HDTV
I have a 2004 RCA HD52W56. When I plug in the green led blink 10 times, stay on for a few second and go off. When I turn it on there's high pitching noise in the back maybe came from the flyback, where the red wires coming in and out on the top of a white box. Does this mean the flyback when bad? because I don't get any picture or sound. Is there a way to test the flyback?
First check to see if you have any voltage at test points with a digital meter.
You may need a repair manual for this.
Since you hear some noise your main fuse is ok.
Try checking this tp voltages first.
BE CAREFUL, wear gloves
